VEHICLE-BRAKE,

Specification of Letters Patent.

Patented April 16, 1907;

Application filed January 15, 1906. Serial No. 296,196-

To all whom, it rim/y concern.-

Be it known that I, ROBERT F. ARMSTRONG, a citizen of the United States,residing at Freeport, in the county of Harrison and State of Ohio, haveinvented certain new and useful Improvements in Vehicle-Brakes, of whichthe following is a specification.

My invention pertains to improvements in vehicle-brakes.

The object of my invention is to provide for readily applying the brakeand for quickly releasing the same and to accomplish these ends in asimple, economic, and effective manner; and it consists of certainstructural. features substantially as hereinafter fully disclosed, andparticularly pointed out by the claim.

In. the accompanying drawings, illustrating the preferred embodimentofmy invention, Figure 1 is a plan view of running-gear employing thesame. Fig. 2 is a vertical longitudinal section produced through therear axle, &c., viewing the brake in edge elevation. Fig. 3 is adetached perspective showing the principal features of the brake.

In carrying out my invention, I employ duplicate metallic brake strapsor bands 1, effective to loosely initially embrace or applied tocircular or annular frictional bearings or collars 2, fixed in anysuitable way to the wheel-lmbs 3 upon their inner portions, and whichmay be leather or like material of the requisite thickness or bulk.These straps or bands of the suitable character to conform. to therequisite impinging as well as yielding action for the intended purposehave each one end firmly looped around a rod or bar member Ayas at 1near its ends, ar ranged parallel with and secured. to the axle 5, asfurther later noted.. The loopsl'" are formed by bending or carryingthese ends of the straps or bands 1 back upon and riveting or otherwisesuitably securing them to the latter, as readily understood. Theopposite ends of the straps or bands 1 are brought opposite to theaforesaid ends thereof after having passed the bands or straps aroundthe frictional collars or bearings 2 and suitably connected or looped,as at 1", to the same rod or bar member 4, so as to permit these ends ofsaid straps to buckle down or be depressed toward said. frictionalcollars as stress is exerted upon said rod or bar member in applying thebrake. The connections 1 are preferably constituted of bail-likeformations or links passed through loops 1, terminating i said rod orbar member and adapted to per-' mit it to freely turn therein, or it maybe otherwise supported in position from said axle. It will be noted thatas the operator grasps and suitably actuates the lever 6,

conveniently arranged for that purpose and connected to rods 6 in turnconnected. to fixed arms 6 oi said rod or bar member 4,

the straps or bands 1 will be caused by the stress or pressure thusexerted upon said. rod or bar to grip or engage the frictional collarsor bearings 2 of the Wheel-hubs for ap plying the brake, and of coursethereby retarding or arresting altogether the action of the wheels orvehicle. l/Vhen stress is taken off the bar or rod member 4 byaccordingly relaxing hold upon the lever, it is apparentthat the brakingaction is relieved.

It will be observed that in this contrivance the collar encompassingbrake straps or bands are drawn or exerted upon, so that their impingingaction is effected wholly through the bar or rod member 4 and not byretaining or securing the ends of each strap or band to a fixture and anactuating rod or bar, respectively, as has in some instance heretoforebeen done, the advantages of the former being obvious.

It is here noted that the bands or straps 1 are designed to be linedwith a leather or some elastic material to prevent noise, while thefrictional collars or bearings 2 may be secured to the wheel-hubs bythree or more set-screws to prevent the warping or distorting of saidcollars or bearings.

I claim- A vehicle brake, employing duplicate brake-straps encompassingwheel-hub collars, hangers or brackets having their inner ends fixed tothe vehicle-axle and their outer ends formed into eyes or loops, a shaftor rod received by said eyes or loops and adapted to turn therein andequipped with. upstanding fixed bails near their ends, said brake-strapshaving their lower ends looped IOO around, and fixed to said rod orshaft and their opposite ends loosely connected to said bails, and saidbails standing astride of the points of connection between said rod or 5shaft and the first-noted ends of said brakestraps.

In testimony whereof I have signed my name to this specification in thepresence of tWo subsorlblng Witnesses.

ROBERT F. ARMSTRONG.
